Storage battery inductive charging device

Abstract

A battery inductive charging device, e.g., a handheld tool battery inductive charging device for a motor vehicle, has at least one charging coil and an high-voltage energy input which is provided to take up a charging energy.

What is claimed is: 
     
         1 . A handheld tool battery inductive charging device for a motor vehicle, comprising:
 at least one charging coil; and   a high-voltage energy input configured to take up charging energy.   
     
     
         2 . The battery inductive charging device as recited in  claim 1 , further comprising:
 at least one voltage transformer configured to transform a voltage of the charging energy present at the high-voltage energy input.   
     
     
         3 . The battery inductive charging device as recited in  claim 2 , further comprising:
 a functional unit configured to control a charging process of the charging coil.   
     
     
         4 . The battery inductive charging device as recited in  claim 3 , further comprising:
 a communications interface which, in at least one operating state, receives at least one energy availability information.   
     
     
         5 . The battery inductive charging device as recited in  claim 4 , wherein the functional unit controls the charging process as a function of the energy availability information. 
     
     
         6 . The battery inductive charging device as recited in  claim 3 , wherein the functional unit controls the charging process as a function of a voltage present at the high-voltage energy input. 
     
     
         7 . The battery inductive charging device as recited in  claim 3 , further comprising:
 a filtering element which minimizes an output of at least one signal having an inductive charging frequency via the high-voltage energy input.   
     
     
         8 . The battery inductive charging device as recited in  claim 3 , further comprising:
 a carrying case holding device which fastens a handheld tool carrying case in a carrying case accommodation region.   
     
     
         9 . The battery inductive charging device as recited in  claim 8 , wherein the charging coil, in at least one operating state, charges a handheld tool battery situated in the carrying case accommodation region. 
     
     
         10 . A system comprising:
 at least one handheld tool battery; and   a battery inductive charging device including:
 at least one charging coil; 
 a high-voltage energy input configured to take up charging energy; 
 at least one voltage transformer configured to transform a voltage of the charging energy present at the high-voltage energy input; 
 a functional unit configured to control a charging process of the charging coil; and 
 a communications interface which, in at least one operating state, receives at least one energy availability information; 
 wherein the functional unit controls the charging process as a function of the energy availability information.
